摘要： 针对浓烟雾遮挡导致消防炮射流轨迹图像识别效果不佳的情况，提出了一种烟雾遮挡下的射流轨迹识别方法。通过混合高斯背景建模射流和烟雾等运动目标进行提取并进行预处理。使用前段射流轨迹识别方法识别前段射流轨迹，该识别方法包括两次判断过程：第一次判断：以相邻列灰度值为255 的点的数量是否发生剧增判断是否发生烟雾遮挡，保留未遮挡部分；第二次判断：计算保留部分中每一列像素值为255 的点的中点坐标，并判断中点坐标是否具有上升趋势。建立射流轨迹方程，并使用前段射流轨迹进行修正，使用轨迹方程代替烟雾遮挡部分的射流轨迹。实验证明，此方法具有良好的识别效果。

Abstract: In view of the poor recognition effect of jet trajectory image caused by dense smoke occlusion, this paper proposes a jet trajectory recognition method under smoke occlusion. Firstly, the moving targets such as jet and smoke are extracted and preprocessed by the mixture Gaussian background modeling;secondly, the front jet trajectory recognition method is used to identify the front jet trajectory. The front jet trajectory recognition method includes two processes: the first is to determine whether the number of points with gray value of 255 in the adjacent column has increased dramatically to determine whether it occurs,and reserve the uncovered part; the second is to calculate the midpoint coordinates of each column of pixel value of 255 in the reserved part, and judge whether the midpoint coordinates have an upward trend. Finally, the jet trajectory equation is established, and the front jet trajectory is modified. The trajectory equation is used to replace the part of jet trajectory covered by smoke. Experiments show that the method proposed in this paper has good recognition effect.
